Painting skill (3)
I believe the answer is:
art
I believe this is a double definition.
'painting' is the first definition.
(painting is an art)
'skill' is the second definition.
(both can mean a talent)
(Other definitions for art that I've seen before include "Cunning" , "Beautiful or significant products of human creativity" , "Creative works; knack" , "Skill in a specified thing" , "Music, painting etc" .)
